    Take a look at the 'rename' function (perldoc -f rename).
    foreach my $file (glob '/path/*.txt') { (my $new_file = $file) =~ s{txt\z}{html}; rename $file => $new_file; }

    To change the file extension is easy, either renaming or i.e:

    use File::Copy; copy("text.txt","text.html")

    But note that this is not the same as to change the type of file.

    So you probably want instead to convert your files to html files, and this is a different problem. Take a look to the module TextToHTML

    If you use GNU the file extension is not really relevant, you could have a jpg named file.txt or file.pdf and will be perfectly recognised as image
